Title: Improvements in and relating to rotary contact seals
IPC: F16J15/36
Filed: 1960-04-14
Abstract: 945,798. Stuffing-box substitutes. U. M. BARSKE, and W. MURRAY. April 14, 1960, No. 13471/60. Heading F2B. A seal between relatively rotatable members, for example, a rotary shaft 1 and a stationary casing 2, comprises an axially movable seal ring 8 sealed to one, 2, of the members by a flexible diaphragm 11 and urged into facial sealing contact with a seal ring 4 fixed to the other member 1 by a circumferential set of juxtaposed leaf-springs 15 fixed together at their outer ends and free at their inner ends. The diaphragm 11 is secured to the ring 8 by a garter spring 13 and is clamped with the outer ends of the springs 15 between the casing 2 and a cover 18. The springs 15 contact the diaphragm on the low-pressure side of the seal and are formed by cutting radial slots 20 in a spring steel ring 21. The seal ring 8 has radial clearance 10 with the shaft 11, is radially supported by the inner edges of the springs 15 and prevented from rotating by a rib 23 on the cover 18 that engages a groove 24 in the seal ring. When the springs are relatively wide, as in Fig. 5, they are supported at their fixed ends along straight lines 22. In a modification, Figs. 7 and 8 (not shown), the springs are supported at their fixed ends on rollers arranged in a circular groove in a clamping ring. In a further modification, Fig. 9, the axially movable seal ring 8 is connected to the casing 2 by three sets of leaf springs 51, 52, 53 and associated diaphragms 54, 55, 56 interconnected by axially movable rings 61 and 62.

Title: Accelerometers
IPC: G01P15/125
Filed: 1961-04-14
Abstract: 935,928. Accelerometers. SPERRY RAND CORPORATION. April 14, 1961 [April 19, 1960], No. 13484/61. Class 40 (1). An accelerometer comprises means for generating a centrifugally restrained fluid surface and means for detecting changes in the surface when the fluid is accelerated along its centrifugal axis. A fluid-filled rotor 10 (Fig. 1), is supported in an outer casing 11 in bearings 15 and consists of plastic members 19, 20 secured to shafts 16, 17. Electrically -conductive discs 26 are embedded in plastic portions 20 and are covered by dielectric material 27, a connector 31 being located on the inner surface of portion 19 to provide electrical connection to the conductive fluid, mercury, contained in the rotor. Slip rings 28, 33 are connected respectively to plates 26 and connector 31. In operation, the rotor is driven through gear 25 to cause the mercury to distribute itself over the inner wall of the rotor as shown, the fluid surface being cylindrical when not accelerated but changing to a parabolic curve under axial acceleration. The area of contact of the mercury with dielectric layer 27 therefore increases at one end by an amount 371 and decreases at the other end by an amount 37. The change in area is detected by measuring the capacitance between plates 26 and the mercury, the change in capacitance being linearly proportional to the acceleration. The difference in capacitance between the end pieces may be determined using the circuit shown in Fig. 3. A capacitative feedback loop provides stabilization. In another embodiment (Fig. 4), a dielectric fluid, e.g. a silicone is used as the inertial mass and is enclosed in a space between a conductive cylinder 45 and a conductive liner 47 of the rotor 10. Conductive discs 26 are again provided but dielectric layers 27 are omitted. Under zero acceleration the fluid fills equal portions of the end spacer 54 but under axial acceleration the fluid is forced partially out of one end space and into the other. A vent 55 is provided to balance the air pressures in the two spaces. The changes in capacitance between end pieces 26 and cylinders 45 are measured using a circuit similar to that shown in Fig. 3 except that the feed-back capacitor 42 is now provided by connecting the output of the amplifier to conductive liner 47. The output is then independent of the dielectric constant of the fluid. The speed of rotation and the viscosity of the fluid are chosen to give optimum damping. Cross-axis sensitivity may be reduced by increasing the centrifugal force developed.

IPC: F16K17/164
Filed: 1955-05-12
Abstract: 809,536. Valves. SPERRYN & CO. Ltd May 10, 1956 [May 12, 1955], No. 13710/55. Class 135. Between the inlet and outlet chambers 4, 5, Fig. 4, is an annular seat 7 with which cooperates a closure member 8 that is secured to a rubber or oiled leather diaphragm 10, the space 12 above which is maintained at atmospheric pressure via a plug 11 whilst a weight 13 screwed on to the underside of the member 8 seats the latter by gravity when the pressure in the outlet chamber 5, acting on the diaphragm 10, is insufficient to overcome the downward pull of the weight. A passage 14, which passes through the weight 13, opens into a chamber 15 defined by a flexible frusto-conical. wall 16 having its upper edge attached to a ring 17 on the valve cover 6 whilst its lower edge is fixed to the centre of the diaphragm 10; pressure from the inlet chamber 4 is transmitted to the chamber 15 and therein exerts a downward force and diaphragm 10 which may be equal to or greater than that acting on the underside of the member 8, depending upon the ratio of the areas concerned. The member 8 can only be reopened by manually operating a spring-loaded valve to allow pressure gas to pass from the inlet to the outlet chamber and by closing cocks in the delivery side. In a modification, the weight is placed on top of the closure member. In another modification the weight is replaced by a spring disposed between the valve cover and closure member. In a further modification, the chamber 15, Fig. 8, is formed by a flexible bellows 31 and the closure member 8 is loosely guided by a depending tube 32 moving in an upstanding sleeve 33, the clearance between the tube and sleeve enabling gas to pass from the inlet chamber 4 to the chamber 15. The space 12 above the diaphragm 10 is connected through a pipe 34 to a flame failure or over-heating warning device 35 associated with the burner supplied with gas from the valve; an orifice 36 in the diaphragm 10 permits a slow escape to atmosphere via the device 35 which escape is closed upon flame failure or overheating, the resulting pressure build-up in the chamber 12 seating the member 8. The orifice 36 may be replaced by a restricted passage by-passing the diaphragm through the body of the assembly. According to the Provisional Specification the by-pass valve may be thermally controlled.
